<p>The EVs are very particular since Rhyperior needs to function in a lot of situations. The 132 Speed EVs give Rhyperior the ability to comfortably outpace base 50s, such as Azumarill and Donphan, while also outrunning minimum Speed base 55s such as Omastar. The 136 HP EVs gives Rhyperior an HP stat of 405, which is a Leftovers number plus another HP so that Rhyperior can create another Substitute. Additionally, Rhyperior makes 101 HP Substitutes so Seismic Toss cannot break them.</p>
Typo... it was "cannon" before though which sounded really funny.
Standard said:
<p>Rhyperior is also a stellar physical wall, especially when against Pokemon without a super effective STAB attack. Using a specially defensive Altaria with Rhyperior works as an effective walling duo, since Altaria resists Water-, Fighting-, Ground-, and Grass-type attacks that would normally destroy Rhyperior, while Rhyperior can take Rock-type attacks and any hard-hitting physical attacker. Ice-type is left uncovered, so using something like Azumarill is beneficial as well.</p>
I think there's an extra line space before this paragraph that needs to be backspaced (there's nothing really wrong with the paragraph... maybe the last sentence needs to start with "the" because the sentence just doesn't sound right at the start).
Rock Polish said:
<p>This set aims to pull off a sweep by doubling Rhyperior's Speed via Rock Polish. After a Rock Polish, Rhyperior outpaces almost every UU Pokemon, including +1 base 80 Speed Pokemon with a neutral nature. Like most sweeping sets, this set functions best when its counters are weakened; (semi-colon) luckily, (comma) Rhyperior does a great job of weakening its own counters. After Rhyperior's counters are weakened, it can set up a Rock Polish and likely sweep the opponent's team with its two 100 Base Power STAB attacks and Megahorn backed by its 379 Attack boosted by Life Orb.</p>
It was pretty much a run-on sentence there. The comma isn't really needed, but I think it makes the flow better.
Choice Band said:
<p>This set aims to break down Rhyperior's usual counters with its Choice Band boosted attacks. Rhyperior can switch into (space) many different attacks because of its impressive bulk, and OHKO many common walls such as Omastar and Steelix. Unlike the other sets, this set uses Stone Edge as its main attack. This is because being locked into Earthquake usually ends up being bad, considering there are so many Pokemon that are immune to it. Stone Edge has no immunities, and even Pokemon that resist it take quite a bit of damage from it. Aqua Tail and Rock Blast can be used in the last slot as situational moves. Donphan and other Rhyperior are hit by Aqua Tail harder than STAB Earthquake. Rock Blast is a great move for countering Substitute abusing Pokemon.</p>
I thought "intomany" was a word at first, but then I looked deeper and saw that it was supposed to be "into many", lol.
"it OHKOes" doesn't necessarily need to be swapped with "OHKO" but it sounds much better.
Avoid using the same word in a row twice (Aqua Tail). I just rearranged the first part of the sentence.
Choice Band said:
<p>While you may be tempted to fire off Earthquakes at every given chance, that is not the best plan when using Rhyperior. Rhyperior's main attack on this set is Stone Edge, especially for early in the game before you know your opponent's team. The reasoning behind this is that no Pokemon is immune to Rock-type attacks, and when you are in a metagame with Pokemon such as Nasty Plot Mismagius, Moltres, Swellow, and Honchkrow, you definitely don't want to be forced to switch out against them. This especially applies for Honchkrow and Swellow since Rhyperior is likely your team's only Flying-type resistance. Once you've taken out the Pokemon who can set up on Ground-type attacks, you are free to use Earthquake, which is always bad news for your opponent. This isn't to say that you should never use Earthquake before your opponent's Pokemon are fainted because hitting Pokemon that wall Stone Edge on the switch with a STAB Earthquake can turn the tide of the match as it will usually OHKO that Pokemon. Stone Edge is simply meant to be used as your main attack.</p>
There needs to be a removal of "Honchkrow" here.
Choice Band said:
<p>This Rhyperior set is an excellent early game hard-hitter since very few Pokemon can stand up to its onslaught of powerful physical attacks. The fact that only a few Pokemon can take a STAB attack from Rhyperior makes it an excellent lure for bulky Pokemon. Rhyperior can also usually OHKO these Pokemon with its other STAB move. For example, Steelix can switch in and shrug off Rhyperior's Stone Edge. However, if it switches into Earthquake, it will be easily OHKOed. This helps Pokemon such as Swellow and Kangaskhan, because without Steelix in their way, they should have a much easier time sweeping.</p>
The second sentence needs the addition of "a" to go with the word "few".
Trick Room said:
<p>This set focuses on abusing Rhyperior's horrible Speed, monstrous Attack, and excellent coverage under the effects of Trick Room. After Trick Room is used, Rhyperior will usually be the "fastest" Pokemon on the field, meaning the opponent needs to survive a 100 Base Power STAB attack before counter-attacking. Additionally, since Rhyperior is so bulky, it can set up Swords Dance and boast an Attack stat of 832, OHKOing the entire metagame.</p>
Missing capitalization.
Trick Room said:
<p>With horrible Speed and an immensely high Attack stat, it is no surprise that Rhyperior is one of the deadliest Trick Room sweepers. The fact that it has perfect coverage from Earthquake, Stone Edge, and Megahorn add to Rhyperior's sweeping capabilities. Swords Dance is a good move to use in the fourth slot since Rhyperior is likely to be bulky enough to pull one off and still have three turns to sweep. After a Swords Dance, Rhyperior will pretty much OHKO the entire tier, and it's no surprise since it will have 832 Attack under its belt. Aqua Tail can be used if you don't like losing a turn of Trick Room to set up Swords Dance, since it hits Donphan and other Rhyperior harder than your other attacks.</p>
"much" > "well" here.
I don't think this is necessary (this isn't related to the above), but can you give a backspace for the [Opinion] area?
Counters said:
<p>Bulky Water-types, (comma instead of period) Pokemon such as Milotic and Blastoise, (comma) can switch into most Rhyperior quite easily and OHKO it with Surf. Defensive Grass-types such as Meganium, Leafeon, and Tangrowth also work quite well, but they need to be wary of Megahorn. Claydol and Torterra are excellent counters as well, since they can easily switch into Rhyperior on any of its STAB attacks. However, similarly to Grass-types, they need to watch out for Megahorn.</p>
Needs comma or doesn't need commas; your choice. This is just mostly here to get rid of the typo period.
